Throwback Thursday: Heart Rate Edition

Throwback Thursday: Heart Rate Edition

Back in college I took a course called 2.671: "Go Forth and Measure". It was all about designing experiments and how to measure results. My culminating project was one I got to create and refine from start to finish. Being a gun girl, I opted to measure the effect of shooting experience on heart rate during rifle practice.

This research was not groundbreaking by any means, but it was a ton of fun to do! My college rifle teammates served as willing "lab rats". 

Here were my conclusions*:

  • Shooters experienced oscillatory heart rate over time, increasing and decreasing periodically around a mean match heart rate.
  • Shooters tended to fire their shots close to the local minimum heart rate.

  • A comparison of the shooters in this study resulted in an "experience factor" of Efactor= 1.7%/year ± 1%/year with 95% certainty gain in percentage of shots fired below mean measured heart rate.

  • Consistency in the time between shots also increased with years of training experience - shooters with more experience got into a rhythm! 

* This was a small sample size, so take these results with a grain of salt! 

I love it when my passions for precision shooting and engineering collide!
